Definitions

  • the invention relates generally to the measurement of surface contours and more particularly to a non-contact apparatus using accordion fringe interferometry (AFI) for the three-dimensional measurement of intra-oral objects.
  • AFI accordion fringe interferometry
  • FIG. 5A shows the displacement of an optical fiber to change the relative phase of the radiation emitted from the two optical fibers of FIG. 4A.
  • FIG. 5D illustrates a different technique for obtaining a relative phase shift.
  • the phase shifter 36 includes a fiber stretch mechanism to stretch one of the optical fibers 14B along a length L while its end remains fixed in location. The stretching alters the physical properties of the fiber 14B such as its length, index of refraction, and birefringence. As a result, the effective optical path length of the fiber 14B is changed and the phase of the radiation emitted from the fiber 14B is changed relative to the phase of the radiation emitted from the other fiber 14 A. This change in the relative phase results in a lateral shift of the fringe pattern as shown, for example, in FIG. 5B and FIG. 5C.
  • the phase shifter 36 includes a fiber compression mechanism to compress or "pinch" one of the optical fibers 14 along a radial fiber axis (i.e., an axis in the x-y plane).
  • FIG. 7 illustrates a structure 62 having axial and lateral flexures for use in an embodiment of an intra-oral device according to the invention.
  • Two single mode optical fibers 14 are fixed by clamps 66 to a substrate 70.
  • the substrate 70 can be fabricated from aluminum or another material depending on the tolerance to temperature variations and fabrication capabilities.
  • Two piezoelectric actuators 74A and 74B are secured to the substrate 70. The actuators 74 provide a means to change the separation distance between the exit ends of the optical fibers 14 and to change the axial position of the exit end of one fiber 14B.

Abstract

L'invention porte sur un procédé et sur un dispositif de détermination d'informations de position tridimensionnelle d'une surface d'un objet translucide ayant des caractéristiques de transmittance et de réflectance dépendant de la longueur d'onde. Le procédé comprend l'éclairage de la surface de l'objet translucide avec un rayonnement optique à une longueur d'onde prédéterminée, émis à partir d'une paire de sources optiques. Le rayonnement diffusé à partir de la surface et depuis le dessous de la surface est détecté, et une phase du rayonnement optique de l'une des sources optiques par rapport à une phase du rayonnement optique de l'autre source optique est modifiée avant de détecter de nouveau le rayonnement diffusé. La longueur d'onde prédéterminée est choisie de telle sorte que le rayonnement optique diffusé depuis le dessous de la surface et détecté fournit une intensité de fond sensiblement constante par rapport au rayonnement optique diffusé à partir de la surface et détecté. Les informations de position tridimensionnelle de la surface sont calculées en réponse au rayonnement détecté.
